Bursitis can happen in any bursa sac in the body, and each type has specific triggers.
The common types of bursitis include:
- Anterior Achilles tendon bursitis (also called Albert disease or retromalleolar bursitis). Caused by things like injury, disease or shoes with rigid back support. This can lead to inflammation of the bursa located where the Achilles tendon attaches to the heel.
- Posterior Achilles tendon bursitis. Occurs in the bursa located between the skin of the heel and the Achilles tendon. It is triggered by walking that presses the soft heel tissue into the hard back support of a shoe like high heels or pumps, and can cause the bone to enlarge at the back of the heel, called a Haglund deformity.
- Hip bursitis, or trochanteric bursitis. Often caused by injury, overuse, arthritis, or surgery. This type of bursitis is more common in women and middle-aged and older adults, and presents on the side of the hip.
- Elbow bursitis. Caused by the inflammation of the bursa located between the skin and bones of the elbow. Elbow bursitis can be caused by injury or constant pressure on the elbow.
- Knee bursitis (also called goosefoot bursitis or Pes Anserine bursitis). The Pes Anserine bursa is located between the shin bone and the three tendons of the hamstring muscles, on the inside of the knee. This type of bursitis may be caused by not stretching before exercise, tight hamstring muscles, being overweight, arthritis, or out-turning of the knee or lower leg.
- Kneecap bursitis, or prepatellar bursitis. Common in people who are on their knees a lot, such as carpet layers and plumbers.
- Septic bursitis. Occurs when a bursa is somehow punctured and bacteria enters it.
